Abstract
Disclosed are highly activated carbon particles derived from caustic digestion of rice hull ash obtained from thermal pyrolysis of rice hulls having an iodine number of at least 650 to 1000. The activated carbon pores are free of silicate residue from the caustic digestion. Also disclosed are methods of removing the silicate residue from the caustic silicate solution during digestion effective to substantially improve the activation of the carbon particles to commercial grade.
Claims
1. In a method for producing activated carbon particles which are separated, by filtration, from a caustic silicate solution produced from caustic digestion of rice hull ash, the ash being obtained from thermal pyrolysis of rice hulls and contains activated carbon particles and pores which contain a silicate residue, the improvement comprising,
(a) washing the filtered activated carbon particles with hot water at temperatures of about
14OT to about 160°F,
(b) washing the resulting damp activated carbon particles from step (a) with an aqueous mineral acid solution eff ctive to dissolve and remove the silicate residue from the pores of the activated carbon particles, and
(c) drying the activated carbon particles from step (b) .
2. The method of Claim 1 where, the aqueous mineral acid solution is selected from the group consisting of an aqueous solution of phosphoric, sulf ric, and hydrochloric acid at concentrations of about 2 percent to about 7 percent by weight mineral acid.
3. The method of Claim 1 where, the dried activated carbon particles of step (c) have iodine numbers at least of 650.
4. The method of Claim 3 where, the dried activated carbon particles of step (c) have iodine numbers from about 650 to 100o.
5. Activated carbon particles having an iodine number of at least 650 and a particle size of not more than 25 microns produced from a caustic digestion of rice hull ash,
the ash being obtained by thermal pyrolysis of rice hulls.
6. The activated carbon particles of Claim 5 where, the activated carbon particles have an iodine number from about 650 to 1000.
7. Activated carbon particles having an iodine number of at least 650 and a particle size of not more than 25 microns produced from a caustic digestion of rice hull ash, the ash being obtained from thermal pyrolysis of rice hulls, said activated carbon particles contain pores which are free of silicate residue.
8. The method of Claim 4 where, the dried activated particles are of a particle size of not more than 25 microns.
9. The method of Claim 4 where, the dried activated particles are of a particle size of not more than 25 microns and of an average size of about 12 microns.
10. The activated carbon particles of claim 7 where, the average particle size of the activated particles is about 12 microns.
